[Houdini Tutorial] 0035 Swarm Intelligence (Slow version)

In this video I'm showing how you can create a flocking simulation as an agent system based on Boids system by Craig Raynolds using Houdini.

This is great, thank you so much for sharing your knowledge! :)

[@massimobaita7178]

Thank You very much, Junichiro!

[@milosgalovic5583]

extraordinary, as always, you're a saint! did you make the one with predators in the meanwhile? (because i need predators x) )

[@affectreflect]

Thank you maestro..Been looking for this since I saw Shifman's processing video on autonomous agents.

[@erfan6101]

exactlyyyyyyy

[@affectreflect]

@@erfan6101 There are also Dop nodes for this behaviour.Pop steer nodes

[@erfan6101]

Affect Reflect DOP is always more complicated than other ways in Houdini :s

[@pixels3314]

thank you so much

[@macben2108]

Thanks!

[@Clairevoyante]

Thank you so much for your video! I was wondering if it would be possible to blend this solver with another solver, like a POP solver, using a multisolver? I love the result of this but I'm trying to figure out the best way to combine this with additional forces, such as a target to reach, or additional wind, turbulence, or path.

Hello I’m a fan of ur tutorials, thanks for all the videos, they are all really helpful. Currently I’m learning grasshopper at school and want to know more about L system, DLA, recursions using only grasshopper, especially using the plugin called ‘Anemone’ which repeats the process. こんにちは、初めまして動画をいつも拝見させてもらっているものです。 現在学校でグラスホッパーを習っているのですが、その中の課題の１つにグラスホッパーだけを使いスウォームインテリジェンス作る課題が出ました。 ネット上ではrese arch seasionを除き、あまりスウォームインテリジェンスの作成方法がのっていませんでした。 DLA, Lsystem, recursionをグラスホッパーのみを使用し、スウォームインテリジェンスを作る動画を作っていただけないでしょうか? いつも動画投稿ありがとうございます。

[@JunichiroHorikawa]

if it's fine using pythonin GH then I could try, since using anemone for swarm intelligence would be pretty slow in terms performance.

[@takoyakidaisuki9010]

That's totally fine! thankyou so much:))

[@ishanshah5970]

Hey man..love your videos... can you make a video on generative designs in grasshopper??

[@JunichiroHorikawa]

Ah I would love to.

[@ishanshah5970]

@@JunichiroHorikawa appreciate it👍

[@BoredomLP]

Well, I am wondering if it is possible to use some more abstract shapes as bounding region. Ofc it is possible in some way but I am not sure how to write it down. Should I use the volume of the boundig object or take the pointinformation and somehow dectectm, if the Agents are inside the volume. How do I do a custome border(edge) detect? U got my sub and perhaps I use ur basic idea for a project for application at university. Excuse my horribly english Greetings from Germany !

[@silenteyes1851]

Hi, I'm in the same boat, wondering how to change the bounding attribute to that of geometry.

[@a--i]

I set parameters and expression same as this video, however i couldn't get same result. Points flied apart, do not gather. Please teach me how to fix it.....

[@StephaneSOUBIRAN]

Thank you ! Could you share the .hip please ? (bcoz file is empty)

[@qazzerful]

grate tutorial. thank you, also it looks like scene file on github contains only empty scene.

[@JunichiroHorikawa]

sorry I've just updated the file.

[@heidi_ye]

can l ask the question? l meet question if i make this turtoral in houdini 19.5,but solver's attribute wrangle can't direction to group type point, so I think this question from to above group, but l saw this node ,can't find the problem, so l want ask you, group type's point,how can dirction to attribute wrangle's run over point

[@AndreaLazzarini79]

Can I ask you why you didn't use a point cloud instead of cycling through all the points?

[@JunichiroHorikawa]

you're totally right, just realized using pcloud is more efficient :p

[@adamyann9300]

handsome!

[@alessandronardini263]

Also, why not implementing this into POP instead of a SOP Solver? You still get the multi threaded performance anyway but inside a full DOP/POP environment! Good job tho!

[@JunichiroHorikawa]

Yeah if I want to use an already implemented physics function then using POP is more efficient I guess. Or if it is going to be faster using POP/DOP then I got to try it.

[@alessandronardini263]

Your cohesion, repulsion and alignment will be the same ( I suggest to use point clouds instead tho ) but being into DOP has its own advantage anyway.

[@Starius2]

teach us the Japanese language too m8! please! you understand English as far as I can tell, so your ability of translation is a valuable thing is making the world better! also I'm in love with ak48, but that can be an excuse elsewhere...

[@JunichiroHorikawa]

I don't really have an idea how I could teach the language, also the use case of Japanese is pretty limited throughout the world I believe.

[@Starius2]

Well m8.... you do realize your country of japan is #3 in the world of economics yes?? it is more valuable then anyone will truly realize! besides..... whats the point of watching anime & gameshows from Japan and not able to understand full context??? also, culture MUST LIVE!! do not let a defeatist conscience to take grasp of you!
